What is an example of testing that can be performed on smoke dampers?

• A. Electronic testing for responsiveness
• B. Visual inspection of closure
• C. Measuring the airflow with gauges
• D. Thermal imaging for heat detection

Answer: (B)

Visual inspection of closure is a crucial testing method for smoke dampers because it ensures that the dampers are functioning as intended to prevent the passage of smoke in the event of a fire. During a visual inspection, the technician checks whether the damper blades close completely and securely without obstruction. This test verifies that the damper will effectively seal off sections of a building to control smoke movement, which is vital for maintaining the integrity of the building’s fire protection strategy. Regular visual inspections help identify physical damage, blockage, or improper installation that could compromise the damper’s operation. This aligns with NFPA standards, which emphasize the importance of maintaining operational integrity for safety and compliance. Other testing methods, while useful in different contexts, do not specifically evaluate the basic functional state of the damper as directly as a visual inspection does. For example, electronic testing may assess response times, measuring airflow gauges pertains to assessing system performance rather than individual damper function, and thermal imaging is more focused on detecting heat rather than ensuring that smoke dampers close properly.
